Deleteing old/past events

I have been using the events calendar for about 2 yrs now and was wondering if there was a way to delete events from 2011 thru abut June 2012 – I do not see any way of doing this. When I go to edit events it only shows those from today forward. I am having malware issues with several links for repeating events I post and was told if I could remove old posts this would help them scan my site faster ( from SiteLock)is this possible to do?

thanks
Jennifer
